"What evidence does Miss An have?"

"The poison the old master is suffering from is a chronic poison. It requires prolonged consumption to take effect. It usually shows no symptoms, and modern medical technology cannot detect it. But once the toxins in the body accumulate to a certain level, the poison will activate, appearing as if it’s a major illness, but with no identifiable symptoms. Young Master Li, if I’m not mistaken, the old master often coughs blood at midnight, right? And he frequently feels very hungry, wanting to eat, but after eating, he coughs blood again at midnight. Am I right?"

A gleam flickered in Li Yuphei’s eyes, but he quickly concealed it.

"Miss An, your reputation as the Divine Doctor is well-deserved."

An Yiqing smiled faintly, "I don’t dare to claim the title of Divine Doctor, but I’ve encountered a similar poison before. This poison can only be administered daily by someone close to the old master. Young Master Li, this matter seems to be quite tricky for the Li Family."

Having someone close to you poison you is hard for anyone to accept, especially for an elder in his sixties who values family relations above all else.

An Yiqing lowered her gaze, her eyes slightly cold. In wealthy mansions, familial love always feels thin.

The room was very quiet. Li Yuphei lowered his eyes in contemplation, and An Yiqing did not speak either. After a long time, Li Yuphei raised his eyes to look at the girl in white.

"Miss An, how can we find out who the poisoner is?"

An Yiqing paused her action of drinking tea, "If Young Master Li trusts me, you can leave it to me. However, this counts as an additional service and will cost extra."

The veins on Li Yuphei’s forehead slightly twitched, and an unexpected smile of helplessness appeared on his otherwise cold face.

"I didn’t expect someone from Miss An’s big and prosperous family to be such a money-grubber."

An Yiqing’s eyebrows curved, "I have many people to support. I can’t not be thrifty."

Li Yuphei gave the girl a deep look, his black eyes narrowing slightly, with an unfathomable expression.

Originally, An Yiqing planned to come to the Li Family during the day to treat the old master and stay with the Thirteen Blood Generals at a hotel at night. However, since the old master was poisoned and not ill, An Yiqing’s plans had to change.

That night, An Yiqing moved into the Li Family Mansion with Zhang Yufeng. Li Yuphei thoughtfully arranged her room in the guest room opposite the old master’s.

"I will stay in the room next door. If Miss An needs anything at night, feel free to call me."

An Yiqing raised an eyebrow, finding his words somehow awkward. What need might she have at night?

She glanced at Li Yuphei, seeing a face of serene calmness with earnest and steady eyes. An Yiqing withdrew her gaze, realizing she might be overthinking it.

"Alright, thank you, Young Master Li."

"No problem, Miss An, please rest first. I won’t disturb you."

Under An Yiqing’s gaze, Li Yuphei turned and left. No one noticed the mysterious smile that played on the man’s lips.

That evening, no one from the Li Family returned for dinner at the mansion. According to the servant in charge of An Yiqing’s living arrangements, the Li Family has three branches, and they usually don’t live there. Only Li Yuphei and the old master live together. Everyone gathers for dinner at the main house on Saturdays, as the old master dislikes noise, so they rarely come during the week.

"Then who is in charge of the old master’s meals and accommodations?" An Yiqing asked, feigning casualness.

"In charge of meals and accommodations?" The caregiver was a young girl with a round, agreeable face. Her clear eyes darted around, giving an impression of innocence rather than craftiness. "The old master has fixed people serving him, Aunt Wu and Butler Uncle Wang. However, during the weekend gatherings, several mistresses will also show off their filial piety."

"Oh? They even cook?" A glint flashed in An Yiqing’s eyes.

The young girl nodded, suddenly lowering her voice, "Miss An, I see you’re an outsider, so let me give you a tip. The weekend is coming, you’ll definitely meet those mistresses. Stay away from them, as both The First Madam and the Third Madam are hard to please."

An Yiqing’s eyes filled with amusement, "Why do you say that?"

The young girl pouted, "The First Madam is very strict and often scolds people with a stern face. The First Young Master is timid and always listens to her. Several times, she has quarreled with the old master when they had differing opinions, leaving the old master trembling with anger, with no help from the First Young Master. As for the Third Madam, she is the biological mother of the Third Young Master. She often takes advantage of his favor with the old master to make a fuss. However, she usually flaunts her fake authority outside. Inside the mansion, with the Third Young Master around, she doesn’t dare."

The Third Young Master the girl mentioned is naturally Li Yuphei. He is the grandson of the family, but calling him the third grandson is awkward, so everyone refers to the eldest son as the First Young Master, while Li Yuphei is known as the Third Young Master.

An Yiqing had heard some things about Li Yuphei’s parents. Li Yuphei’s father is the old master’s third son, an average person without much capability. He currently serves as a nominal general manager in the Li Group, drawing annual dividends but having no significant achievements. His mother, Lin Yufen, came from an ordinary family but was quite scheming and managed to marry Li Laosan, becoming part of the Li Family and giving birth to Li Yuphei.

At that time, when Li Yuphei was born, the children of the first and second branch had already matured. The child of the first branch was ten years old, being aggressive and competitive. The child of the second branch was eight, introverted, showing signs of autism, and unsuitable for the cutthroat business world. So, after Li Yuphei’s birth, Li Yuhang decisively took him in for personal upbringing, ensuring he didn’t inherit the vices of his third branch parents.

No mother would willingly give up her newborn, but Lin Yufen showed no reaction at all. She played and enjoyed herself as if she never had the child. Over the years, apart from weekend gatherings, she’s rarely visited Li Yuphei.

Fortunately, Li Yuhang, as a grandfather, was always very good to Li Yuphei. Though his father was incompetent and timid, he served as an adequate father, occasionally visiting the mansion to see the son who held great expectations.

Snapping back to reality, An Yiqing blinked and looked at the young girl, "I remember the old master has four children. What about the youngest one?"

The young girl was taken aback, "You mean the Fourth Miss? She’s always been abroad and only returned recently due to the old master’s illness. She’s been to the mansion twice and doesn’t seem to like talking much."

An Yiqing raised an eyebrow. Li Yuhang has three sons and one daughter, and being the youngest child means that the old master naturally pampered his daughter, Li Zihe. However, after falling in love with someone from Country Zi, she moved there after marriage.
